President, Maximum Sports Management

He doesn’t get the face time that Drew Rosenhaus gets, but Eugene Parker puts his money where his mouth is. Parker has milked NFL owners for over $2 billion, including the massive $13 million signing bonus he negotiated for Deion Sanders via the Dallas Cowboys. At the time, the biggest signing bonus in the NFL was Troy Aikman’s $7 million.

Other previous players and future Hall of Famers on Parker’s client list include Emmitt Smith, Curtis Martin and Rod Woodson.
